The first bottle dates back from before 1938, as the logo –the N encircled by the lifebuoy—shows. The ad, from 1929, shows a similar bottle in the background.It holds, apparently, 14 fluid ounces (about 400 ml) for one single yen.

The second bottle is also depicted in an ad, this time from 1950. For JPY 270 one could get 24 fl. oz. (about 700 ml) of fountain pen ink, also suitable for general purposes. The price for smaller quantities is displayed on the wooden frame: 1 oz (a little less than 30 ml) for JPY 30, and 2 oz for JPY 50.
